Eye-blink conditioning is associated with changes in synaptic ultrastructure in the rabbit interpositus nuclei

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number.     

Religious Toleration and Organisational Typologies

In Britain at least, secularisation has proceeded to the point where the characteristics that conventionally divide churches, denominations, sects, and cults as types of religious organisation have largely disappeared. Drawing on survey data and newspaper reports collected over the last three decades, we argue that societal hostility now focuses so narrowly on tangential aspects of religion that the characteristic of existing in a high degree of tension with the wider environment (which is central to most definitions of the sect) is increasingly rare and is now likely to be applied to churches and denominations. The article concludes with a suggestion for a new typology.     

The motivating potential of teams: Test and extension of cross-level model of motivation in teams

Although individual- and team-level studies of motivational processes abound, very few have sought to link such phenomena across levels. Filling this gap, we build upon Chen and Kanfer’s (2006) multilevel theoretical model of motivation in teams, to advance and test a cross-level model of relationships between individual and team motivation and performance. Data from two samples of undergraduates performing simulated team tasks supported the direct and mediated cross-level relationships between team-level prior performance, efficacy, and action processes with individual-level self-efficacy, goal striving, and performance. The findings provide support for a multilevel, system-based formulation of motivation and performance in teams. Findings also contribute to the on-going debate on whether motivational processes account for performance once controlling for prior performance.     

Loneliness,Interpersonal Distrust,and Alexithymia in University Students1

Loneliness has been linked to emotional knowledge and interpersonal distrust, but it is unknown whether it is mediated or moderated by these variables. Using self‐report measures, the relationship between loneliness, interpersonal distrust, and alexithymia was investigated in undergraduate students (N = 224). Analyses showed a direct relationship between alexithymia and social, family, and romantic loneliness. We also found that interpersonal distrust partly mediates this relationship, and that alexithymia and interpersonal distrust interacted to predict social and family loneliness. These findings suggest that links between the different facets of alexithymia, interpersonal distrust, and loneliness are complex and multifaceted, and they are discussed with regard to interventions for young adults.     

Impact of auditory selective attention on verbal short-term memory and vocabulary development

This study investigated the role of auditory selective attention capacities as a possible mediator of the well-established association between verbal short-term memory (STM) and vocabulary development. A total of 47 6- and 7-year-olds were administered verbal immediate serial recall and auditory attention tasks. Both task types probed processing of item and serial order information because recent studies have shown this distinction to be critical when exploring relations between STM and lexical development. Multiple regression and variance partitioning analyses highlighted two variables as determinants of vocabulary development: (a) a serial order processing variable shared by STM order recall and a selective attention task for sequence information and (b) an attentional variable shared by selective attention measures targeting item or sequence information. The current study highlights the need for integrative STM models, accounting for conjoined influences of attentional capacities and serial order processing capacities on STM performance and the establishment of the lexical language network.     

Forgiveness,Reconciliation, and Mechila: Integrating the Jewish Concept of Forgiveness Into Clinical Practice

The professional literature diverges in defining the role of forgiveness and reconciliation in counseling regarding how forgiveness and reconciliation are conceptualized from a professional and secular perspective. The Jewish conceptualization of forgiveness is multifaceted; mechila, the forgiveness of debt, is particularly important in providing a framework for forgiveness when the issue of reconciliation is involved. The authors offer an explanation of the Jewish conceptualization of forgiveness and discuss a way to infuse the concept of mechila into counseling practice on a broader level with all clients.     

French categorization norms for 70 semantic categories and comparison with Van Overschelde et al.’s (2004) English norms

The present methodological note provides categorization norms for 70 semantic categories collected from 200 participants. The categories were mainly derived from a French translation of the Van Overschelde, Rawson, and Dunlosky (2004) inductor terms including a large set of semantic categories. Our study also extends recent French norms (Léger, Boumlak, & Tijus, 2008; Marchal & Nicolas, 2003) and tests their stability. These 70 categories constitute the widest French categorization norms to date and will be of use to studies in the fields of both linguistics and psycholinguistics. A cross-linguistic comparison, with both quantitative and qualitative results, is also performed, which should prove useful for bilingual and/or cross-linguistic studies. The norms collected for all 70 categories are available for download as supplemental materials from http://brm.psychonomic-journals.org/content/supplemental.     

The Supernatural and the Miraculous

Both intention-based and causation-based definitions of the miraculous make reference to the term ‘supernatural’. Philosophers who define the miraculous appear to use this term in a loose way, perhaps meaning the nonnatural, perhaps meaning a subcategory of the nonnatural. Here I examine the aetiology of the term ‘supernatural’. I consider three outstanding issues regarding the meaning of the term and conclude that the supernatural is best understood as a subcategory of the nonnatural. In light of this clarification, I argue that a prominent causation-based definition of the miraculous should be revised so as not refer to the supernatural. I further argue that authors of intention-based definitions of the miraculous need to consider whether or not they should continue to refer to the supernatural, in their definitions of the miraculous, in light of the conclusions discerned here.
